Make no mistake, Nephrogenic Systemic Fibrosis (NSF), a horrible (and thankfully very rare) disease which can afflict persons with significantly impaired kidney function who receive certain gadolinium based MRI contrast agents. Over the past few years, tremendous resources have been poured into the identification of patients, research on the specific mechanisms of disease, and effective means of prevention. NSF has run into a problem, however, which has dramatically curtailed further research… we’ve darn-near eliminated this disease!
A few weeks ago I posted my layperson’s summary of why there’s even an issue with metal and MRI (click here to read that post on MRI and Metal). In this posting, I hope to explain why it’s so critical to find metals, particularly ferromagnetic metals, being carried by people or inside objects.
